T0 ALL WHOM IT MAY CONCERN:

Be it known thalt we J. E. WINANTS of Brooklyn, county cf Kings, and Sta.te of' New York, und JOHN F. GRIFFEN, of New York, county und State of New York, have invented eert ain new and useful Izhprovements in Manufaeturing Tnrpentine; und we do her6by declare that the following is a full and exact; description thereof, reference belng had to the aceompanying drawings, making pa.rt 'of this application.

Our i'nvention relates to certain, new am]. useful improvements in the distillation of turpentine, and in the appara.tus for melting the erude material und carrying 011 ehe process of distillation.

Previou s 110 our invention it has been customary, in the process of distilling crude turpentine and other material, to 'employ a retort in whioh the crude material has been heated to a sfiicient temperature to produce evaparation, and which retort ha.s been made with a. goose-neck extending up from the dome of the retort, ai1 thro'ugh which goose-neck the produots of'-distillation were ca.rried ofi to the condenser.

We have found, by experiment, that: the vapors of trpentine ar'1d oil are heavler tha.n air, and thnt in rarefying such vapors sufliciently, by increasing tlieir temperature, to enable them-to ascend into and thro1lgh the goose-neck, the retort has to be so highly l1eated as to burn or materiallyinjurethe rosin or other residuum in the fetort, und to avoid this damage to the' rosin, and a1: the same time economize hea.t, anti more successfully carry on the process cf distilling turpentine, are tlge main objects of the first part of our invention, which consists in carrying on the distillation at a. comparatively low temperature, and allowing the vapors 120 escape and pa.ss oft ata. point just above or below the solid contents of the still.

A'nd our inven'tion further conslsts in a still composed.of a. rota.tory steam-heated cylin'der, through which the crude m aterial is passed in a, st'ate of agitation, and which is arranged within a. suitable case, provided with an inlet for the crutle materia.l and outlets for tl1e products of distillation und rosin, or residuum, as will be presently explained.

And our invention further consists in an improved apparatus for melting the Cllld8 turpentlne ouf; of the barrels, feedixig it to the still, nnd for drying tl1e barrels, all as hereafter more fully explaixied.

'lo enable those skilled inthe art to make and use nur invention, we willproceed to describe it more fully, referring by letters to the accompanying drawings, in which Figure 1 is n perspective view of our improved melting a.nd distilling-appamtus.

Fignre 2 is a vertical longitudinal secliion of the still.

Figure 3 is a vertica.l section of melting-apparatus.

Fignre 4 is a. pla.n view, showing the arrangement of the steam-plpes of melting-apparatus, a.nd

Figure 5 is a. detail cross-section of the still stea.m-cylinder. 7

In the several figures the sa.me parts are designated by the same letters cf refenence.

A is the melting-chamber, wl1ich is composed of a removable cylindrical case, B, which rests 011 a double bottom or ca'se, C, supported by standards D at a. suitable height relatively to the still..

'lhis doubl bottom or case C is provided with internal stea.m-tubes d, which are supplied from a stemmpipe, D", and t-h a case C is provided with an exh ziust-pipe e, through which tl1e steam passes ifl from said case. The steam-tubes 0Z are arranged in a. peculiar manner, a.nd perforated, as will be presently more fully explainecl- F i's a. series 0f conical,barrel-supporteis, wlxich extend upvtard from the steam-czyse C, a.nd bn which the barrels of crud turpentine arepla.ced upside down, the heated coxxes penetrating contents of the barrels, as illustrated a t fig. 3. f

G i s' tl1e czgse 0x still-cham'ber, in which tbe distillation is efiected. It is a simple tight case, suitably supported, umlprovided with an outlet or exit-pipef, near one end, for tl1e disclmrge of tl1e rosin, und with a pipe, h, through which tl1e fumes or vapors of turpentine pnss ofl to any suitable condensing-apparatus. Witl:lin the caseG is arranged a stea.m-heated rotaryflylinder, H, which ismounted on a hollow steam-shaft, a, having suitable bearing's where il: passes through the isnds of ca.se G, und provided with a Pulley ab g, by means of which it is rotated.

This eylinder H is formed, as shown, with an openingat one end, through which tl1 e melted Made turpen- 'tine is discl1arged from tl1e supply-pipe z into the interior of sai(l cylinclex, und is left entirely open anti flared atj, ab the obher end, to permic the free ischarge of tl1e material passecl through.

The cylinder H is providetl inside with loxigitudinally-arrange ste' am-pipes, k k, eommunicating by mea.ns f the radial sheam-arms lwith the central or axia.l steam-pipe or sl1aft a. Stea .m is supplied te the sha.ft a, and circulates througll all the steam-tubes, as indicated by tl1e red arrows, and the cru le material from the melting-apparatus asses from tlxe la.tter into the steam-eylinder, and. thrqugh it, :Ls 'indicated. by the bla.ck arrows in the drawing.

That end of tl1e dylin ler H into which the melted material is fed maybe eleva.ted smewhat'above the level of tlxe otl1er end, if deemed expedientto fa.oilitate tl1e Passage of tl1e matei*ial through sai cylinder. We propose to place over the mouth of th exib of the melting-chainber a. suitable filter o1 strainer, m, to prevent the assage, into the pipe z, of chips or other matter whioh might log it up. We hav e representa'ad als 1'1; n 1 ;he barrels of crude turpentine as arranged 011 the melting-cones F. These steanci-heated Cones are of a sufiicient height to leave a space benea.th the mouth of the inverted barrel ample for the free exii. from the la.tter of its contents as it is melterl out. is a. pipe, to allow the fumes of melted material to palss into any condenser.

Th e steam-tubes in the melting-chamber case G 2.1e so arra.sxge with vertical branches perforatecl all around, extending up into the cones F a.nd radial bmn'ches cP, perfo'rated only er! top, as to ejecl; the live steam only on 1:6 those surfaces 6f the melting-apparatus whieh are in contact with l:he crude material to be melte, and consequently the hea.t f the lieam is mosl: advautageously sind ecoriomically-applied.

\ The general operati m of the whole apparatus mag be tlqu s-bfiefiy explained:

The cones F being' supplied with barrels ofcrude turpentlne, am]. tl1e case B placedover thern, witl1 its nase resting in a. trough supplied with water, prevent the vapor's pa.ssing oub, a sufcient head of live stea m put on to the melting-apPamtus, a.nd alo on to the still, antl tl1 e rotat ory stea.mcylincler H put in motion, tlxe crudle turpentine 'will be melted out of the harre] gradually and tlmrqglaly, and passing through the strainer m, und

' thence an through tl1e supply-pipe z, will be dischargeint l tlxe cylinder H. Asthis cylinder revolves, witl1 its steam-heated pipes k k gmd arms Z.l, tl1e contained materia.l Will be thomughly and constantly agita.ted and tumbled by the pipes k k an l arms during its assage through said oylinder, so. tlia.t only the -resiluum will be left be discharge d ab the outlet-end cf seid cylinder..ll the volatile portions of the turpentine being vaporized or (listilled out efi'ectually by the sai(ls team-heated -zm l agita.fiing-cylind er. The proclucts of distilla.tion will all.pass olf through the pipe k, from which they are conklucted to 'the condenser, while the rosin asses olf into any suitble receptacle thro ug h the exit-pipe f.

Whenever it is necessary to replenish the m'elting-chamber, the cylindrical case B is removed, am]. a fresh supply of filled barrels put in. In meluin out the crude turpentine from lihe barrels oh the steam-cones F,

- not only the entire connents of the barrels may 'be exhausted, but the barrels :nay be quite dried auf; clea.n.

' It will be understood that by thepyocess and apparatus describecl, we me ena.bl'edl 120 thoro ughly distill tl1e turpentine from the cr ude mterialat a bompamtively low temperature to tl1e solid portion of tl1e mass, thus :woiding any burningor injury 120 the ros sin. The solid material, being continua.lly agitated amlbroughfl in to fresh co'ntact with heated-surfaces, hat; all fahle turpentine disaiiled oul; witl1wt a.ny excessive aud injurious hea.t and 'thus no t only is the process more economically conclucted, but more uccessfully, and with better results.

B y performing the o peration of distillation in tl1e manner describerl, a.z1d a1; a 10W temperature irl tl1e mass, in lieu of h ati'ng the 1i1ass highly, and causing it to boil up,'as is customary, in the retort, sd thata. gooseneck has be used, -we a.re e nabledlo ca.rry ofi' tlre products of distillation a.t a point low down, and consequently more completely' extract the turpentine, wl1ile a1; the Same time, we carry little or no foreign matter to tl1e gondenser, sind-cum pf'oduce a lzirger percentage '0f l1d purertxirpenine from the Same quantity anti quality ol crude turpentine'than ca.n be clone by any o ther process or apparatus k1iown tb'us.

Of course the details of construction of Ehe apparatus ma.y be veried, und modifica.tions may be made in carrying out the evera.l characteristic fea.h;res of our improvements, without depa.rting from the spirit of our inver'xtion. 7

Ha.ving described our invention so that i hose skilled in the an can fully underta.nd and praot.ise it, what we cla.im a.s nev v, and desire to secure by Letters. Patent,is

1. The proc6ss, substantially asflescribed,.of distilling the crude material a.ud extractiugthe fumes at a. low temperature, am]. carrying tl1em olf from the 10Wer portion of t;l1e still, as a.nd for the purposes sei; forth.

2. Also, the em plyment, in c'o mbination with the cha.mber or ca.se ofthe still, of a. stea.-heated rota.ting agitator -cylinder into und through which the-fude ina.teria.l asses during the process of distillaltion, substzuitially as described.

3. Also',-the employme'nt, in combinatien with theinelting-chamber, of one or mre hea.tecl barrel-Supporters, F, ada.plzed to hold a.nd melt out tl1e c'ontents of the barrels, substautially a hereinbefore described.

4. Also, tl1e emplaymwf of steamtubes so perfdralzecl a.s to ejeefr the live steam on to those surfa.ces which are required to radia.te the grea.test quantity of hea.t, subta.ntially as herein sei: forth.

' In testimony whereof, we have here unto Set our ha.pds a.nd seals, this 28ch.dhy of March, 1868.
